RESUMEN
The chromato-mass-spectrometric studies of volatile emissions of fresh-cut roses have revealed the persistence of wide range of organic compounds. The most large content was consist of terpene hydrocarbons. The contribution of oxygen-containing components (alcohols, ethers, aldehydes and ketones) varied in wide ranges in dependence on the content of the feeding solution. The significant part of plants ' volatiles has no hygienic norm. Among the substances released into the air space ofpremises with volatile emissions ofplants, a significant part has not hygienic standards. Purposeful change in composition of the mixture of volatile organic compounds released by the plants, in the combination with chemical-analytical control of the content of these substances by gas chromatography-mass spectrometry in terms of ecological and hygienic aspects may be useful in the development, use and determination of the optimal conditions of the implementation of environment improving phytotechnologies and evaluation of the efficacy and safety of their impact on public health.
